The terrifying thriller tells the story of Sara (Lydia Bosch, 'Grand Hotel'), a popular novelist who after suffering a serious accident, it is host to a monastery in the north section of Italy in which dwells an ancient brotherhood. A place stuck in the past: without light, water or telephone, where the Benedictine monks, sitting in the dark, cold and silent, strictly follow the laws of Christianity.
